such as a car key.
2. Flip the bottom seat cushion forward by
pulling up on the tab located in the center
of the seat cushion where the seatback meets
the seat cushion. There is a tab on both
rear seats.
Make sure the front seats are not reclined.
If they are, the seat cushion will not flip forward
completely.
